How to Use Gmail with Custom Domain: Using POP3 and Forwarders

Do you own a custom domain email, but want to use Gmail as the main platform to manage all messages? You’ve come to the right place. Stick with us and discover how to integrate your custom domain address with Gmail.

Reasons to Integrate Custom Domain Email to Gmail Account

When you buy hosting, chances are you’ll get a free business email right out of the box. However, it might take time to get used to because the interface is different from Gmail’s.

There are numerous options available for setting up a professional email account. While purchasing a Google Workspace account is one alternative, requiring an investment with plans starting at $6/month per user, other email services offer more budget-friendly solutions, with some starting as low as $0.99/month.

Luckily, it’s possible to use Gmail with your own domains for free. That way, you can have the best of both worlds — a custom domain email with the convenience of Gmail’s interface. You also don’t have to log in to different platforms to manage your personal and business emails.

How to Integrate a Custom Domain Email to Gmail?

Now that you know why it’s convenient to integrate Gmail with a custom domain, let’s take a look at the steps to set it up:

1.  Getting POP3 and SMTP Details

Before we can set up a Gmail account to work with a custom domain, first you need to create a domain-based email. In case you haven’t made one, refer to our tutorial to know how to do so.

After creating the email, you need to collect its POP3 and SMTP details. To locate the email protocols in Hostinger’s hPanel, do the following:

  1. Head over to Email Accounts under the Emails section.
  2. Select Configuration settings.
  1. Select Manual Configuration. We’re going to use that information later.

2.  Forwarding Emails to Gmail Account

Now that we have the necessary data, it’s time to set up the Gmail account so it can receive messages sent to your custom domain email. Here’s how:

  1. Log in to your Gmail account, click on the gear icon, and select Settings -> Accounts and Import.
  2. Choose Add a mail account under the Check mail from other accounts section.
  3. After you enter your domain email, click Next -> Import emails from my other account (POP3) -> Next.
  4. Fill in the details using the server information we located earlier. The server we’re using is, and the port is 995.
    This is how you set up gmail with your custom domain to receive messages.
  5. Check the boxes as needed, but we recommend ticking the first three boxes. This way, you can keep two copies of the same message on different platforms, use a secure connection, and label incoming messages according to their original email destination.
  6. Click Add Account to finalize the settings.
  7. You’ll be prompted with the option to send emails from your custom address. If you only need Gmail to receive emails and choose No, you’ll be all set. But if you want the platform to be your one-stop destination to receive and send messages, select Yes and continue to the next part.
    This is the message prompt that will allow you to set up gmail to send emails from your custom domain.

3.  Configuring Gmail to Send Emails as a Custom Domain

  1. Enter your name and email address and leave the Treat as an alias box checked. This way, you can manage incoming and outgoing messages from the same inbox as your current Gmail address. Click Next.
  2. Set the as the SMTP server and 465 as the port. Use TLS to secure the connection.
